Retails for around $280 Canadian.
I just tested one of those out last week, I was very impressed!
Is there anywhere in Ontario that carries these. I have yet to see one and would like to have a look at one. For the size of the head on it you could remove the high limit and have easy access to the heat exchangers or pop a hole under the a-coil to check for dirty coils.
Honestly, this tool is useless. The quality of the picture is really no good.
The Inspector® > SeeSnake Micro™
I was a little disgruntled when I saw this on the shelf of the wholesaler about 3 weeks after speding $400 on the Testo scope that just has the eyepiece no LCD screen. You are right though. The picture quality is a little off. The one good thing I can say about mine is that the quality is awesome as the are no degrading electronics inolved. It's completely a none electronic optical device.

I was impresses with the testo one at a convention in Toronto. Quite frankly the inspector is awesome but not $1200 more awesome. I saw the rigid at home depot a couple days ago for just under $200 if I remember right.
